Phase 7: Advanced Infrastructure
Designing systems is one thing. Running them in production is another. Learn observability, serverless, Kubernetes, service mesh, and chaos engineering.
Observability Stack
Distributed tracing (Jaeger), metrics (Prometheus), logs (ELK). The three pillars of observability.
Serverless Architecture
AWS Lambda, Cloud Functions. Cold starts, scaling, and when to go serverless.
Container Orchestration
Kubernetes fundamentals. Pods, services, deployments, and scaling strategies.
Service Mesh
Istio, Linkerd. Traffic management, observability, and security for microservices.
Chaos Engineering
Netflix's Simian Army, Gremlin. Testing resilience by injecting failures.
Deployment Strategies
Blue-green, canary releases, feature flags. Zero-downtime deployments.
Job Schedulers
Apache Airflow, Temporal. Orchestrating workflows and distributed cron.
Background Workers
Celery, Sidekiq, Bull. Async task processing and job queues.
Secrets Management
HashiCorp Vault, AWS Secrets Manager. Secure credential storage and rotation.
Circuit Breakers
Hystrix, resilience4j. Preventing cascading failures with fault tolerance patterns.
